4Ah vs. 5Ah Batteries: What's the Difference?
Introduction Ah, or ampere-hours, is a unit of electrical charge capacity. It is equal to the amount of current (in amperes) that can be drawn from a battery for one hour. So, a 4Ah battery can provide 4 amperes of current for one hour, or 2 amperes of current for two hours, and so on. 5Ah batteries have a slightly higher capacity than 4Ah batteries, meaning they can provide more current for a longer period of time....
